The present work is meant to investigate wave-induced global loads in a ship in realistic flooding conditions. The scenarios investigated are represented by water ingress into the forepeak and/or the portside ballast tanks of a 150,000 DWT double hull tanker in a laden condition. Seakeeping computations are performed in six flooding situations, each corresponding to different changes in displacement, trim and heel. For each of them, the wave-induced global loads and hull motions are computed in terms of response amplitude operators, using a three-dimensional linear potential seakeeping code in the frequency domain. The results, showing significant variations in the global loads with respect to the intact ship, are reported and commented on in view of their possible use in the definition of design loads for checks of the longitudinal strength of ships in accidental conditions.

Abstract

The present work is meant to investigate wave-induced global loads in a ship in realistic flooding conditions. The scenarios investigated are represented by water ingress into the forepeak and/or the portside ballast tanks of a 150,000 DWT double hull tanker in a laden condition. Seakeeping computations are performed in six flooding situations, each corresponding to different changes in displacement, trim and heel. For each of them, the wave-induced global loads and hull motions are computed in terms of response amplitude operators, using a three-dimensional linear potential seakeeping code in the frequency domain. The results, showing significant variations in the global loads with respect to the intact ship, are reported and commented on in view of their possible use in the definition of design loads for checks of the longitudinal strength of ships in accidental conditions.
